Question

Glucose-Fructose mixture concentration was 73 µg/mL. what is the concentration of glucose in the mixture? total volume = 25ml

Answer 1

Glucose and Fructose are structural isomers having molecular formula C₆H₁₂O₆.

Let us assume that the mixture contains glucose and fructose in x:y ratio respectively. The concentration of the mixture is 73 µg/mL. Then total weight of 25 mL mixture is,

                                    (73 µg/mL)*(25 mL) = 1825 µg

Thus, glucose content of the mixture is,

                                    (1825 µg)*[x/(x+y)] = [(1825x)/(x+y)] µg

Therefore, the concentration of glucose in the 25 mL mixture is,

                        [(1825x)/(x+y)] µg / (25 mL) = [(73x)/(x+y)] µg/mL

Hence, if the ratio content of the mixture is known then the concentration of the glucose in the mixture can be determined accordingly.
